FOX releases poster for 250th episode of ‘Family Guy’

Manny v Pacquiao? Nope. Aliens vs Predator? Nuh uh. The biggest fight of the century is Peter Griffin vs Liam Neeson (Batman Begins) in an upcoming episode of Family Guy!
Peter claims he would beat Liam Neeson (guest voice Liam Neeson) in a fight, but when he is put to the test, he learns that winning is tougher than it seems. Meanwhile, Stewie becomes jealous when Lois decides to be a class mom and starts paying more attention to the other kids over him in the all-new “Fighting Irish” 250th episode of FAMILY GUY.
The episode will air on May 3rd @ 9 pm ET/PT, check your local listings. Check out the first poster here.
"There are also other characters that come and go (also owned by the Warner Bros. Discovery conglomerate media company)."
Huh. Is that just referring to other characters from the show itself, or is this implying that the new season is going to have cameos from other WBD IPs
